* suggesting this for inclusion into the icon naming specification
** not in the spec, but let's keep it out of there anyways,
it's not really suited to be a standard icon
*** exists in the Tango icon set, but not in the spec

Generic Tango icons in Oxygen:

krfb -> preferences-desktop-remote-desktop
(also used in GNOME under that name)

Other application icons:

Most other application icons should go to their home modules instead of residing in kdelibs - this not only makes for a better overview but also reduces disk space in case not all modules are installed. And, of course, prevents icons being misused for wrong usages.

To do for Oxygen

Icons that are in the spec, but not yet in Oxygen's apps/ (after renaming) so they need to be added. Descriptions taken from the specification.

preferences-desktop-multimedia
The icon used for the desktop's multimedia preferences.

To do for Oxygen - not in the spec

Icons that are not specified and do not currently exist as well, but are needed for KDE applications (and not blatantly obvious). Yes, I am aware that some of those are bad (if not outright evil) names. That comes from preferences-desktop-peripherals being classified in the "desktop" preferences subgroup, which is very wrong imho. We need to fix this in the spec (see the suggestions of the categories page), but until then, I stay with specification conform names.

preferences-desktop-effect **
The icon for the "Desktop Effects" KCM. (New in KDE 4.)
preferences-desktop-panel **
The icon for the "Panels" KCM.
preferences-desktop-theme-style **
The icon for the "Style" KCM (widget style, in "Appearance").
preferences-system-network-discovery **
The icon for the "Service Discovery"
(= DNSSD / Zeroconf / Bonjour / Rendezvous) KCM.
preferences-system-network-proxy ***
The icon for the "Proxy" KCM. (Also exists in the Tango set.)
preferences-system-session ***
The icon for the "Session Manager" KCM.
(This icon also exists in the Tango set.)
preferences-system-splash **
The icon for the "Splash Screen" KCM.

Optional icons

We don't absolutely need those because they are covered by fallbacks: if these icons don't exist, they've got a sensible fallback.

preferences-desktop-display-multiple
The icon for the "Multiple Monitors" (aka Xinerama) KCM.
preferences-desktop-display-randr
The icon for the "Size & Orientation" KCM.
preferences-desktop-keyboard-khotkeys
The icon for the "KHotKeys" KCM.
preferences-desktop-multiple
The icon for the "Multiple Desktops"
(a.k.a. virtual desktops) KCM.
preferences-desktop-panel-taskbar
The icon for the "Taskbar" KCM.
preferences-desktop-user-account
The icon for the "Password & User Account" KCM.
preferences-desktop-user-smartcard
The icon for the "Smartcards" KCM.
(Was "identity" in KDE 3, and is really not necessary.)
preferences-system-solid
The icon for the "Solid" KCM. (New in KDE 4.)
preferences-system-network-connection
The icon for the "Connection Preferences" KCM.
preferences-system-network-share-windows
The icon for the "Windows Shares" KCM.
preferences-system-network-share-windows-status
The icon for the "Samba Status" KCM (in KInfoCenter).
preferences-system-windows-effect
The icon for the "Window Effects" KCM. (New in KDE 4.)
preferences-system-windows-decoration
The icon for the "Window Decorations" KCM.
preferences-system-windows-specific
The icon for the "Window-Specific Settings" KCM.

Even more optional

Draw those only if you feel like wasting time for
little outcome. I haven't got KDE 4 compiled at the moment,
so I don't even know if those are visible at all.

preferences-system-windows-focus
The icon for the KWin's "Focus" settings, which
belong to the "Window Behaviour" KCM.
preferences-system-windows-action
The icon for the KWin's "Actions" settings, which
belong to the "Window Behaviour" KCM.
preferences-system-windows-movement
The icon for the KWin's "Moving" settings, which
belong to the "Window Behaviour" KCM.
preferences-system-windows-advanced
The icon for the KWin's "Advanced" settings, which
belong to the "Window Behaviour" KCM.

Icons in Tango, but not in the spec

We don't need to have those, but if we do they should be named this way:

internet-group-chat
For a possible generic instant messager icon.
*Very* optional though, as we already have branded
Kopete and Konversation icons.
internet-mail
We already have this from the previous "kmail" icon.
internet-news-reader
Instead of "knode".
internet-web-browser
For a possible generic browser icon. *Very* optional though,
as we already have a branded Konqueror icon. (Done.)
office-calendar
We already have this from the previous "korganizer" icon.
(Done.)
preferences-desktop-assistive-technology
Tango does this as preferences-desktop-accessibility
plus an emblem-style gear icon at the lower right.
Hardly necessary to have.
preferences-desktop-sound
Go Phonon go. (Done.)
preferences-system-network-proxy
We do have proxy settings in KDE 3, this might make sense.
preferences-system-session
The icon for the session management settings.
preferences-system-windows
KWin settings. (Done.)
system-installer
Adept, Yast, Pirut, Smart, or whatever else is out there.
system-users
Seems to fit KUser or Guidance's "User Management" module.
(Evaluate if actions/users can be moved here.)
